Dealing with Fever in Newborns
Adults can keep their body temperature at a normal level because they have a tightly controlled thermostat.When you are cold, you shiver, helping to raise your body temperature. When you are overheated, you sweat to help you cool off. However this mechanism is not completely developed in newborns. Newborns lack the insulating fat layer that older babies and children have . As a result a newborn may not have a fever with an infection. Fevers in babies are usually caused by something more serious. You need to call your doctor right away if your baby is younger than 3 months old and has a rectal temperature of 100.4°F (38°C) or higher.
